Thanks i do like a lot tour videos very useful and easy to understand i use it when i want to explain car things to my wife
I do the exact same thing
Thanks EE. I’ll share this “thoughts” with my wife
Does the gear shift selector fork issue still apply if you have a fwd car that is shifted by a cable?
Yes it does - the cable still transfers the force on the gearstick to the shift forks.
Yes. You’re still moving a shift fork ultimately. The image from the owners manual in the video is from the Evo X, which uses cable guides for the transverse engine.
Great video! But I have to disagree with Nr. 4… of course you can’t accelerate hard in a high gear, but when you only want to speed up slightly, the most efficient way is to keep the car in a high gear and apply almost full throttle! This way, you are reducing the throttle losses, which increases the efficiency. I can’t think of any negative effects this could have…
NO … downshift, accelerate, upshift. The end. When you smash the throttle on a higher gear with JUST ENOUGH rpm so you maintain your speed: First its gonna take longer until you reach the desired speed. Second, you’re gona burn more fuel, just because the engine needs to do harder work, thus needs more fuel, so throttle needs to be pressed deeper AND for longer amount of time.
This isn’t about efficiency. This is about saving components. Giving a lot of throttle in high gear puts excessive wear on your engine. Just because the RPM is low doesn’t mean you aren’t putting a high amount of stress on the engine when you floor it in high gear. It could be argued that it could wear parts out more quickly than when flooring it in a lower gear because you are forcing the engine to work its hardest while also forcing it to work with the mechanical disadvantage of being in a high gear. Also, because of that mechanical disadvantage you will use just as much fuel as flooring it in a lower gear. So downshifting is actually more efficient since you wont have to hit the accelerator as hard to achieve the same speed as you would in a higher gear.
Try it while datalogging an aggressively tuned engine and watch the knock cell counts.
This is literally one of the reasons why ringland failure occurs in Subarus.
Definitely not true, yes you can accelerate but it puts extra stress on your engine. This is especially true in a turbocharged car.
You didint push the Ebrake button when you use ebrake…. You don’t respect your car !!! Not a car guy obvious…
It’s a ratchet, same mechanism is used in a socket wrench (which you hear every time you use it). It’ll be fine haha. If that part’s toast, the car has likely been toast for years.
Pretty sure this guy knows more about cars than almost this whole website combined. He could’ve done it on accident. I’ve looked it up. It is perfectly fine to pull the handbrake without pressing the button. It won’t cause more wear than it’s supposed to. Mr. Jason AKA Engineering Explained am I right?
It looks like YOU are not the car guy
Haha, you know your car is awesome when you don’t need to make noises with your mouth when you accelerate 😂
You win the internet.
But the desire is still there, subconsciously I can’t help myself haha.
I always do BOV sounds tho cause force induction is life 😂😂😂😂😂😂
“Don’t rest your hand on the gear shift”. I can hear Initial D fanboys stroking out in the distance.
Now I know! Thanks for that, I wasn’t aware I shouldn’t rest my hand on the gear knob.. Or leave it in gear at the lights. I will change how I drive from this vid!
I saw this dude at a red light that was slightly uphill, he was driving a slammed NB miata (looked awesome) and he just sat there rocking back and forth for a solid 30 seconds. What a scrub. Also, if your engine has thrust washers on the crankshaft, leaving the clutch in brings premature wear to the thrust washers, increasing crank end float, and ultimately scoring the rear side of the crankshaft.
Great tips! I’m guilty of all 5 and altough I already knew all those things it’s just habits that’s hard too get rid of. Definitely going to have these in my head after watching this though!
